Customizable 40mm/42mm Round Sapphire Watch Case In Magenta

Customizable 40mm/42mm Round Sapphire Watch Case in Magenta

Sapphire (α-Al₂O₃), as the second hardest material after diamond (Mohs hardness 9), has become the material of choice for high-end watch cases due to its exceptional scratch resistance and brilliant optical properties. Utilizing advanced crystal growth and precision machining technologies, we craft sapphire into stunningly colorful watch cases, dials, and jewelry, offering a range of customizable hues including red, blue, yellow, pink, black, and more to meet personalized design demands. As an integrated manufacturer and trader, ZMSH not only supply premium sapphire raw materials but also provide end-to-end customization services—from design to finished product—supporting custom orders based on client drawings to create truly unique horological artistry.

Key Features of sapphire watch case

1. Ultimate Scratch Resistance
With a Mohs hardness of 9, sapphire watch cases resist scratches from daily wear and sharp objects, maintaining a mirror-like finish far superior to traditional mineral glass or ceramic materials.

2. Crystal-Clear Transparency
Exceptional light transmittance (≥85% in the visible spectrum) ensures optimal dial legibility, while color coating techniques deliver gemstone-like depth and brilliance.

3. Luxurious Yet Lightweight
The polished surface achieves a liquid-metal smoothness, and its density (3.98g/cm³) is lower than stainless steel, reducing watch weight while enhancing wearability.

4. Chemically Inert & Durable
Resistant to acids, alkalis, and corrosion, it retains vibrant colors even with prolonged exposure to sweat or cosmetics, eliminating oxidation issues common in metal cases.
